Referring more particularly to {the drawings, the'numeral 1 indicatesthe body of my improveddispensing device which is provided with ,ahorizontal partition 2 to form a lower compartment 3 in which aremovable receptacle l is arranged. This receptacle 4 is preferably ofmetal and is adapted to contain ice or other suitable cooling mediumwhich rests upon the floor plate 5, said fioor plate having perforations'6 therein whereby the liquid from the ice as it melts will passdownwardly on to the bottom of the receptacle 1 and then pass outthrough any suitable discharge pipe or. the receptacle 4; may beremovedand placed in an inverted position for removing the water. 7

This receptacle 1 is movable through an openin ,7 formed in the frontwall of the body 1 and is provided with stop flanges 8 Wherebyto limitthe inward sliding movement of the same. The outer end ofthe receptacleis provided with a'handle 9 whereby the same may be quickly and readilyre moved and replaced when desired.

The upper portion of the body 1 is provided with longitudinal partitions10 forming chambers 11 upon opposite sides of the center of the bodyproviding cooling chambers for frozen confection placed in the removablecontainer 12. The side walls of the removable container 12 are providedwith longitudinal grooves 13 adapted to receive the tongues 14 along theedges of the emovab'le cover 15, said cover normally closing the upperopen side of the container '12.

Extend'ng upwardly from the body 1 upon theopposite sides of the centerthere e the spaced ds 1.6 their upper ends threaded as at 17 andremovably mounted upon these studs is the top piece 18 adapted to besecurely retained in position by means of the wing nuts 19 threaded uponthe studs 16. The top piece 18 is provided with an opening 22, saidopening being provided with shoulders 20 adapted to cooperate with theshoulders on the removable cover plate 21. The cover plate 21 ispreferably rectangular in form, as shown in Figure 3, and is adapted tonormally close the opening 22 formed 11] the top piece 18, thus when itis desired to fill the container 12 with the frozen confection the cover21 is removed and the cover plate 15 pulled outwardly a sutlicientdistance to permit the confection to be placed in the con tainer 12through the opening 22. In order to facilitate removal of the coverplate 15, a handle 23 is attached to the outer end thereof, as isclearly illustrated in Figure 3.

In order to dispense the frozen confection from the container 12, apiston 21 is mounted therein and preferablyofashape to fit the container12 and has connected thereto a threaded stem 25 which extends through anopening in one wall of the body and into a tubular guide 26. The piston2-1 is provided at the edges thereof with cutaway portions 27 formingtransverse cutting edges 28 which will cut and remove from the walls ofthe receptacle 12 any of the frozen confeetion which has atendency toadhere thereto.

In order to force the piston 21 through the container 12, a bevelledgear 29 is mounted upon the stem 25 of the piston 2i and is adapted tomesh with a similar gear 30 on a stub shaft 31. The stub shaft 31 alsocarries a second bevelled gear 32 which meshes with a similar gear 33 onthe longitudinal shaft 3%, the shaft 3-1- carrying second gear 35adapted to mesh with a gea- 36 on the operating shaft 37, said operatingshaft being supported in any suitable manner within the body 1 with oneend thereof extending through one wall of the body and having ahandwheel 38 attached thereto for manually imparting movementto theshaft 37 and thus impart movement to the piston 2 through the connectiondisclosed above.

The dispensing means whereby the frozen. confection may be dispensed inpredetermined quant-ities into edible containers or the like, includes abody member 39 having a longitudinal chamber -10 therethrough and isfurther provided with a transverse opens iug 1-1 which communicates withone end of the container 12 whereby upon forward movement of the piston24: in the container 12, a sufficient quantity of frozenconfection willbe forced into the dispensing device prior to dispensing the sametherefrom.

iirranged within the longitudinal chamber 10, in the body 39, is acylindrical casing 12 which is spaced from the walls of the chauibcr i lby means of annular ribs :2) an 2111 suitable type of cooling iiceiliembe placed in the space bet'w 9-2 and the wall of the chamber ltlountedupon the top of the arranged over the upper end of 1 4 0,11 {Zuidecasing and slidu upon this casing is a disc 4!; ha slots -17 to receivethe arcuate portion of the casing 17 whereby the disc to is ably mountedupon the casing and has connected thereto a plurality of .7 "le rods l!)which are mountet for reciprocating more ment within the bores hunted inthe body 39. The disc -lt3 has connected therrto at a central pointtheplunger rod 51 which is dctachably connected to the iilungcr 5:3.

The plunger 52 fits snugly within the cylinder and provided with acentral bore whereby the rod 51 will extend through the plunger and haveits inner end flush with the; inner end of the plunger, as is clearlyillustrated in F1 The plunger 52 is dctacluihly (:(lllllttctetl to therod and th plunger may be tthlG ly and readily connected orlir=cminected with respect to the rod 51 so that the plunger will remainstationary during the reciprocatory movement of the rod or whenconnected thereto the plunger and rod will move simultaneously.

The plunger 52 is provided with t versely threaded openings 5:; in whithreaded pins 51 are mounted, sun. having reduced portions 53 at eachthereof, the inner ends of said p transversely of the openii 53 and havemounted therein the discs which have threaded connection with the pinsthe peripheral edges of said discs extendin above the upper end oi theplunger as shown in Figure 2 whereby they may be readily rotated by handso as to ad iust th pins longitudinally in the, openings for connectingand diseonnertiu the rod til with respect to the ]'ilItEl;3 '0i' lt' wilbe apparent that when it is desired to disconnect the rod 5;!

It will he ing member i t thi tterthe plunge coil springs 6 i moveddown which placed 11- e ion leased, i

ion the sp body 39 is provddcc with a reduced threaded shoulder 62adapted to be engaged by he annular threaded flange 63 formed upon tieguiding and Shapi point I wish to call attention to the tact tha while Ihave shown and described the shapi 1g member as being provided with acylindrical opening, it will be readily apparent that this member may bereplaced by other members bearing difierent shapes and Vde'e'ns ofopenings so that t a 11G confection may be dispensed througl i theshaping member in various predetermined designs,

it will be noted that the bottom of the body member 1 has an extensionplate and mounted upon this plate is a rotatable uprightsha'it 66, theupper end of which engaged within an opening 67 formed in the shoulder68, said opening having a spring 69 therein which normally bears againstthe upper end of the shaft. Loosely mounted upon the lower end of theshaft 66 1s a cam member 70 having atapered engaging portion 71 anddisposed above the cam member 70 is a second cam member 72 which isconnected to the shaft and rotatable therewith and is provided withtapered recess 73 forming a shoulder 7 against which the rotatableportion 71 engages.

The can 70 has projecting outwardly therefrom an arm 75 to the outer endof which is connected a socket 7 6 which is aoapted to carry the shell77 to be filled from the -cylinder 42. The shaft 66 has extendedoutwardly therefrom at approximately its central portion an angularbracket 78 to the up; or end of which is attached a stopper T9 adaptedto be fitted into the recess in the lower face of the shaping member 6%.

From the above it will be apparent that when the machine is not in use,the stopper 79' is arranged within the recess 80 ot the shaping memberin order to prevent the contents of the body 3 9 from becoming reducedto a liquid state. The relative positions of 'the bracket 78 and arm 75,when the stopper 79 is in an operative position, are disclosed in Figure6. From this it will be noted that when the arm 75 is disposed at theright-hand side of the body 39 and the tapered point 71 is removed fromthe recess 73 it will retain the shaft 66 in a raised position againstthe tension of the spring 77 so asvto retain the stopper 79 in therecess 80. When it is desired to remove the stopper and position thesocket 76' beneath the shaping member 6 the arm 75: is moved toward thebracket 78', this movementbringingthe tapered point *Zl into the recess'73 which will permit the upper cam 72, to-' gether with the shaft 66,to drop downwardly, disengaging the stopper 79 from the. recess andfurther continued movement of the arm 75 will rotate the upper cam 72 soas to move the stopper 79 entirely out trom beneath the opening in theshaping member. It will be apparent that as soon as the tapered point 71reached the shoulder 74 in the recess 73, the tension of the spring 67will move the shaft 66 downwardly and permit further rotation of theparts connected to the shaft so as to properly position the stopper 79and socket 76.

It will be apparent from the foregoing that I have provided an ice creamdispensing device which is especially adapted for use in filling ediblecontainers and wherein a great o antity of these containers may bequickly and readily filled by hand. In the general operation of myimproved device the container 12 is filled through the opening in thetop of the body, with the piston 24 in its outermost position, as shownin Figure 2. has been tilled, and the machine ready for operation, thepiston 24 is moved forwardly in the container through the rotation ofthe handwheel 38 and for theconvenience of the operator an indicatingmember 81 is attached to the bearing of the handwheel 38 and suitableindicating members may be applied to the side of the housing 1 so thatthe operator may readily ascertain the proper amount of movement for thehandwheel 38 in order to till the cylinder 42 and it will also beapparent that by the use of the indicatino numbers the o orator mareadil members at the discharge end of the dis charging mechanism, camactuated means adapted to normally close the discharge end and to bemanually operated to remove the same from and into position beneath theguiding and shaping members and a receptacle tor receiving the frozenconfection from the discharging mechanism.

2. A machine of the character described including feeding nievhanism,discharging mechanism including a receiving chamber, a. guiding andshaping member at the discharge end of said chamber, an uprightrotatable shaft adjacent the discharge end of said rhaznber. a stoppercarried bfvsaid-alnii't and nor-mall positioned against the guiding andshaping members to close the discharge opening, a supporting membermounted on the shaft and means whereby upon rotation of said shaft thestopper will be removed from engagement with the guiding and shapingmembers and a Supporting member moved into position beneath the guidingand shaping member.

in testimony whereof I ai'iix my signature.
